The AquaCare Twin is very useful for the removal of old composite restorations.
Hold the cutting nozzle at an angle of about 45 degrees to the surface of the old
composite restoration and about 2mm or 3mm from the surface.
The best approach is to use a slow circular motion over the old restoration
beginning at the edge, particularly at the failed margin, until all the old composite has
been removed and the cavity preparation completed.
The new restorative can now be applied in the normal manner without any further
treatment. Follow the manufacturer’s recommendations with regard to the use of acid
etch with bonding systems.
